92 CHAPTER 2: DIAL PLAN
Conference Calls Involving Site Codes and Off-Site Telephones
In Figure 29
, you work in the Chicago office and want to establish a
conference call with someone in Atlanta, someone in Dallas, and
someone at an external telephone number, you:
1 Dial the Atlanta site code (62) and then the extension.
2 After the Atlanta user answers, press Conference and dial the Dallas site
code (63) and then the extension.
3 When the Dallas user answers, press Conference again to connect all
three users.

If the site requires that you dial 9 to reach an outside telephone line, and
if the call is a long-distance call, the user might dial a number in area
code 367 using the digit sequence 913675551212.
5 When the person answers, press Conference again to connect all four
users.
How to Configure a
Virtual Tie Line
Configuring a working VTL connection between two systems involves:
■ License Installation
■ Dial Plan Configuration
■ Verification of the Virtual Tie Line
License Installation ■ You must obtain a license for VTLs. License levels are 2, 4, or 8 VTLs on
the NBX 100 system, and 2, 4, 8, 16, 24, or 48 VTLs on a SuperStack 3
NBX system.
■ Each VTL license applies only to the NBX system on which it is
installed. To connect three sites by VTLs and to have each site support
up to 8 simultaneous active VTL connections, you must install a
separate license key for 8 VTLs on each of the three NBX systems.
■ To increase the number of VTLs above one of the levels on a system,
you must add one or more incremental licenses of 2 VTLs each.
To install a VTL license:
1 In the NBX NetSet - Main Menu window, click Operations. Click the
Licenses tab and the Add License button. In the text boxes, type the
license key code.
2 Click OK and then restart the NBX system.
